The poll, by the Democratic firm Public Policy Polling, found 51 percent of all respondents view Christie favorably while 23 percent see him unfavorably.

Among Democrats, 52 percent have a favorable impression of Christie while 23 percent have an unfavorable one. Among Republicans, 48 percent have favorable view and 27 percent have an unfavorable view. From last month, Christie’s standing among Democrats has improved by 12 points, while his standing among Republicans has declined by 11 points, according to pollster Tom Jensen.

Jensen said Christie’s change in popularity with members of both parties most likely stems from a nationally televised press conference last week in which he slammed House Speaker John Boehner (R-Ohio) for delaying a vote on aid to recover from Hurricane Sandy.

“I think the change from last month is probably mostly about the Boehner stuff, but I think the longer term change is certainly all the positive national publicity he got for how he handled the hurricane but also specifically how he dealt with Obama,” said Jensen.

Jensen said his organization will release a poll tomorrow on the potential field for the Republican presidential nomination in 2016. He said Christie does well among moderate Republicans but has virtually no support from the tea party members.

Among all voters, Christie is more popular than Senate Majority Leader Harry Reid (D-Nev.), former GOP presidential nominee Mitt Romney, Senate Minority Leader Mitch McConnell (R-Ky.) and the National Rifle Association.

The automated telephone poll of 1,100 registered voters was conducted from Jan. 3 to Jan. 6 and has a margin of error of plus or minus 3 percentage points.
